S43.121D Dislocation of right acromioclavicular joint, 100%-200% displacement, subsequent encounter

Name of the Condition

• Dislocation of Right Acromioclavicular Joint, 100%-200% Displacement, Subsequent Encounter

Summary

This condition describes a complete dislocation of the right acromioclavicular (AC) joint with 100%-200% displacement, occurring during a subsequent encounter for treatment. The clavicle is displaced from the acromion of the scapula by 100% to 200% of its normal width, typically resulting from trauma. It may cause pain, instability, or restricted shoulder movement, and requires ongoing management during follow-up visits.

Causes

Traumatic events such as falls, direct blows to the shoulder, or forceful movements can cause this dislocation. Common triggers include sports injuries, motor vehicle accidents, or falls. The subsequent encounter indicates the patient is receiving ongoing care for the injury.

Risk Factors

• Participation in contact sports or activities with high fall risk.
• Previous shoulder injuries or ligamentous instability.
• Age-related degeneration or connective tissue disorders.
• Occupations requiring repetitive arm or shoulder movements.

Symptoms

• Pain and tenderness around the top of the shoulder.
• Visible deformity or swelling over the acromioclavicular joint.
• Limited range of motion in the shoulder.
• Sensation of the joint "popping out" or feeling unstable.

Diagnosis

Diagnosis typically involves a physical examination to assess tenderness, deformity, and range of motion. Imaging tests like X-rays may be used to confirm displacement and rule out fractures. The "subsequent encounter" designation indicates the patient is being seen for follow-up care after the initial injury.

Treatment Options

• Non-surgical treatments such as rest, ice, and physical therapy to restore function.
• Pain management with medications or injections.
• Surgical intervention may be considered for persistent instability or severe cases.
• Ongoing monitoring to assess healing and adjust treatment plans.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and adherence to treatment. Most patients recover with appropriate care, though some may experience long-term shoulder instability. Follow-up visits are essential to monitor progress, adjust therapy, and address any complications.

Complications

• Chronic shoulder pain or instability.
• Nerve or blood vessel damage in severe cases.
• Delayed healing or malunion.
• Recurrent dislocation.

Lifestyle & Prevention

• Avoid activities that strain the shoulder until fully healed.
• Use protective gear during sports or high-risk activities.
• Strengthen shoulder muscles through targeted exercises.
• Maintain a healthy weight to reduce joint stress.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or inability to move the shoulder. Contact a healthcare provider if symptoms worsen or new issues arise during recovery.

Tips for Medical Coders

Document the "subsequent encounter" status clearly, indicating the patient is receiving active treatment for the dislocation. Include details about the displacement percentage (100%-200%) and the affected side (right) to ensure accurate coding. Note any ongoing therapies or follow-up care to support the subsequent encounter designation.
